TOGGLE.

Application filed April 25, 1924. SerialNo. 709,064;

My invention relatesto certain improvementsin toggles vfor'attaching leather, or

other material, to frames so that a proper drying will be effected. A l

The object of the invention 1s to simphfy the construction of the toggle so that it can be manufactured cheaply, and to design it so that the material to be dried will be held firmly, yet will not come in contact with the supporting frame.

In the accompanying drawmgs l Fig. 1 is a perspective view of my Improved toggle;

Fig. 2 is a sectional view;

Fig. 3 is a side view, showing the clamp in the open position; Y

Fig. et is a side View of the toggle and the supporting frame and leather; in section, the clamp firmly holding the leather;

Fig. 5 is a sectional view on the line l5 5, Fi 2; Y, v

ig. 6 is an enlarged sectional view of part of Fig. 4;

Fig. 7 is a view of the blank forming the body of the toggle before bending; and

Fi 8 is a view of the blank from which the c amp is formed.

Referring to the drawings, 1 is the body of the toggle and 2 is the clamp. The body is made of sheet metal, of the form shown in Fig. 7. This blank 1a has lateral projections 3*, which are perforated at 4 and form the rforated brackets 3 of the toggle. The fileank is punched at 5 to form a tongue 5, which is bent outwards and is shaped to enter one of the perforations 6 in the sup orting frame 7. The frame 7 may be made of) perforated metal or of wire netting.

c The body blank 1 is bent on the lines b,

c and d, and is shaped to form a raised gripping surface at one'end, as shown in Fig. 2.

Grooves 8 are pressed into the blank, which' act to form gripping surfaces for the leather and the pressing of the materialto form'the grooves produces ribs, which tend to strengthen the toggle at the point Where pressure is applied. The two ends of the lank overlap at 9 and may be secured together by welding, or other means. p

The curved portion 10 of the -body is crimped to strengthenthe toggle at this point together, said tubular bo ingtheleathe'r on the-fram` and to form a neat handv hold used in stretch-` vThe clamp 2 is made from a sheetdnietal blank 2a, Fig. 8, and has lateral projections 11a, which form the trunnions 11 of the clamp.' These trunnions'extend through the perforations in the brackets 3 of the body of the toggle. On the sides of the clamp are stop lugs 12, which limit the opening movement of the clamp, as shown in Fi 3. The clamp is inthe form of a cam and as a portion 13, which bears against the surface of the leather and forces it a ainst the grooved gripping surface 14 of t e body. As the leather is pulled, the clamp tightens its hold thereon.

By shaping the toggle in the manner shown, the material being dried is held awayv from the supporting frame.

I claim :V

1. The combination in a toggle, of a body portion composed of sheet metal and comprising a base, a hand hold formed inte al with said base at one end thereof, a ralsed gripping surface formed integral with said base at the opposite end thereof, brackets formed integral with said body portion and respectively located at the opposite sides of said raised gripping surface, and a clamp pivotally mounted in and between said integral brackets andbent to form a cam which is adapted to engage the material and hold it against the said raised gripping surface of the body portion. x

2. The combination Yin a toggle, of a body portion composed of sheet metal bent into tubularv form with overla ping edges secured y portioncomprising a base, a hand hold formed integral with said base at one end thereof, a raised gripping surface formed integral with said base at the opposite end thereof, brackets formed integral with said body portion intermediate the hand hold-andY the raised grippingV surface and respectively .located at the opposite'sides of said raised gripping surface, and a clamp pivotally mounted in and between said integral brackets and bent to form a camwhich A portion composed of sheet metal and comprising a base, a hand hold formed integral with apart'transversely of said fiat gripping` surf face, brackets formedintegral With said body portion and respectively located at the oppo-V site sides of said raised gripping surface, and a clamp pivotally mounted in and between y said integral brackets and bent to form a cani .which is adapted to engage the material and hold it against the!V said raised flat gripping surface of the body portion, and to force the said material into the longitudinal. grooves formed in said raised fiat gripping surface.

4. The combination in a toggle, of a body portion made of sheet metal having a flat base provided with a Vtongue to extend through a support, said body. portion being bent to form a grippingsurface on a different plane frointhe base so as to hold thelmaterial somedistance fromtlie support; brackets formed integral with the saidbody'portion and projecting on each side of the gripping surface; and a clamp in theform of a cam and pivotally mounted on the brackets and arranged to press the material against the gripping surface of the toggle. v v
